In this work, we study magnetization switching induced by spin-orbit torque in heterostructures with variable thickness of heavy-metal layers W and Pt, perpendicularly magnetized Co layer and an antiferromagnetic NiO layer. Using current-driven switching, magnetoresistance and anomalous Hall effect measurements, perpendicular and in-plane exchange bias field were determined. Several Hall-bar devices possessing in-plane exchange bias from both systems were selected and analyzed in relation to…

Strong Interfacial Perpendicular Magnetic Anisotropy in Exchange-Biased NiO/Co/Au and NiO/Co/NiO Layered Systems

It is shown that the coercive and EB fields increase significantly when the Co layer is coupled with two NiO layers, instead of one, and a wide-ranging control of the exchange bias field is demonstrated without perturbing other magnetic properties of importance.
